My boys are 12,13 and 15 and I sometimes will take one with me...I have seen smaller children, but there is always another adult with them...I would definitely get a sitter for your first donation though...mine took 4 hours
They have to be a certain age to wait in the lobby. I let my 11 year old stepson come with me sometimes when his mom's at work. And I'm well-known up there. I've been donating since April.
